vApplication filed May 11,1903. Serial No. 156,550. (No model.) l

To @ZZ whom t may con/cerro: i e' Beit known that I, HENRY C. BLACK, acitizen of the United States, residing in the cityl and county of SanFrancisco, State of California, have invented certain new and usefulImprovements in Can Body Forming and Seaming Machines; and Ido herebydeclare the following to be a full, clear, and exact description of thesame.

The presentinvention relates more particularly to certain improvementsvupon the canbody forming and seaming machine set forth and described inthe application, Serial No.

116,951, filed by mein the United States Patent Office on the 25th dayof July, 1902, theirnprovements residing in the anvil-bar around whichthe can-body blanks are formed, the construction of the endless carrierfor propelling the can-bodies through the machine whereby theseam'er-horns ordinarily employed are dispensed with, and in theconnections for supporting the formed bodies as conveyed from theanvil-bar toward thedischarge end of the machine. The means employed forfeeding the can-body blanks into the machine and folding the saidcan-body blanks about the anvil-bar, for imparting an intermittentnon-reciprocating movement to the endless carrier, for forming theinterlocking hooks in the side edges of the can-bodies, and closing theside seam of the can-bodies is substantially the same as the.corresponding means fully set forth in my aforesaid application,Wherefore the same Will only be briefly referred to in the presentapplication.

'Io comprehend the invention, reference should be had to theaccompanying sheets of drawings, wherein- Figure 1 is a side View of themachine in elevation. Fig. 2 is a top plan View of the mechanismdisclosed in Fig. 1 of the drawings, the endless carrier being brokenaway. Fig. 3 is an end view in elevation viewed from the feed end of themachine, the endless carrier being partly broken away and the curved endguides therefor being removed. Fig. 4 is a cross-'sectional View, in endelevation, on line b b, Figs. 1 and 2 of the drawings, the anvil-barbcingillustrated in position, the endless carrier, the drive mechanism,and the drive-disks being removed. Fig. 5 is a simidrawings, theanvil-bar and the endless carrier being illustrated in position. Fig. 6is a detail sectional View disclosing the hookforming mechanism for theside edges of the can-bodies.' Fig. 7 is a top plan View of the anvil-bar. Fig. 8 is a cross-sectional end view of the anvil-bar, taken online z z, Fig. 7 of the drawings; and Fig. 9 is a similar view taken online a a on Fig. 7 of the drawings, said View disclosing the gage-ribfor holding the rolled-can-body separated, the can-body being brokenaway, and illustrating the oscillatory rod located Within the anvil-bar.The frame of the machine comprises a suitable bed 1, to which lthe endsupports 2 3 are bolted, said end supports being united by the sidepieces 4. 4.. These side pieces are formed with the inwardly-projectingflanges 5, which support the upper run of the hereinafter-describedendless` carrier.

Within bearings ofthe end supports 3 works a cross-shaft 5', to whichthe disks 6 6 are secured. These disks serve as drive-disks for theendless carrier, which carrier consists of a series of frames or links7, hinged together by bolts 7. To the projecting ends of each connectingbolt or pin 7' the rollers 8 are secured, which rollers flt withinsegment-seats 8', cut in the periphery of each of the drivedisks andride upon the supporting-flanges 5 of the side pieces, inside of theguides 9, up-

wardly projecting from each supportingflange 5. These rollers also rideupon the guide-rails 9' 92, secured tothe end supports 2 3, which railsare located a short distance below the supporting-flanges 5 and serve tosupport the under run of the endless carrier.

At the feed end of the machine these guide-- at their upper 'ends carryt'he inwardly-.extending brackets 12.

Each frame or link is also formed intermediate the arms 1l 12 with acentrally-projecting tongue 13.

ABetween the ears 13', depending from the curved bracket 132 near thefeed end of the machine, is hinged the anvil-bar 14. This lar view takenon line c c, Figs. 1 and 2 of the bar extends approximately the lengthof the IOC machine, the same being held in horizontal alinement by theendless carrier. The brackets 12 fit within the guideways 14, cut in thecylindrical portion of the anvil-bar, while the stud or tongue 13 workswithin the central guideway 142, cut in the under face of the saidanvil-bar. Said anvil-bar is preferably rectangular in shape incross-section, except at such portion thereof whereon the lockseam ofthe can-bodies is closed by the hammer. At such point the said anvil-baris cylindrical in shape, so as to completely fill the interior of thecylindrical can-body while the side seam is being closed.

At one side of the machine, at what I term the feed end,is located thefeed-guide 15 for the can-body blanks, which can-body blanks aredelivered between the feed-rolls 15 152, located above the anvil-bar, bythe feed-conveyer 16, working within the feed-guide 15. As the can-bodyblanks are conveyed through the feed-rolls they are deflected downwardby the plate 16, so as to curl around the anvilbar 14, the side edges ofthe curled blank being held apart 0r separated by the gage-rib 17,projecting above the said anvil-bar. The moment the can-body blank hasbeen curled or rolled around the anvil-bar 14 the endless carrier isgiven an intermittentforward movement. Inasmuch as the brackets 12' andtongue 13 bear against the outer end or edge of the rolled can-bodyblank the said blank is advanced or moved upon the anvil-bar 14 until itis placed and brought to rest immediately beneath the hook-forming die17. During this movement the free edges of the can-body blanks are helddown to prevent springing upward by means of the guideplate 18.

In the face of the anvil-bar in line with the die 17 is inserted thedie-block 172, in which are formed the grooves 18' 182, which groovesare formed on each side of a series of pins 19 and in shape correspondwith the male and female hook-sections of the die 17. 'As thehook-forming die is moved downward the side edges of the can-body blanksare forced into the groove 18' 182 in order to form theinterlocking-hooks 20 20'. After the formation of the interlocking hooksin the side edges of the can-body the can-body blank is forced along theanvil-bar by the intermittent movement of the endless carrier until thesame is placed beneath the hammer 21. During the movement of thecan-body blank from the hook-forming mechanism toward the hammer 21 thefree edges of the can-body pass beneath the guide 22, one of the sideedges of the canbody as moved thereunder being gradually forced overuntil the hook 2O is placed into engagement with the hook 20'. Y Section22' of the anvil-bar, immediately beneath the hammer 21, is cylindricalin cross-section. As the can-body blank is received onto this p0rtion ofthe anvil-bar its temporarily-closed seam will rest above thelongitudinal groove 23 in the face of the anvil-plate 23', fitted withina seat 24 cut in section 22 of the anvil-bar. As the hammer 21 isbrought down onto the side seam to firmly close the interlocked hooksthe anvil or hammer plate 23' is moved vertically or upwardly a slightdistance in order to fill out or true the canbody circumferentially.This movement of the anvil or hammer plate is obtained by means of theeccentric portion 24' of an oscillatory rod 25, which rod extendsthrough and works within a central opening 25' in the anvil-bar. Thisrod 25 is oscillared within the anvil-bar to raise the anvil or hammerplate 23' at the proper moment by means of the connecting-link 26, Figs.2 and 3 of the drawings. One end of this link is connected to acrank-head 26', secured to the outer projecting end of the' oscillatoryrod 25, while the opposite end is attached to the free end of thefulcrumed link 27. From this lever projects a stud or pin 27', whichworks within an irregular-shaped groove cut in the inner face of the cam272, secured to the forward end of the longitudinal shaft 28. The shaft28 carries two cams 28 282, which actuate, respectively, the arms 29 29.These arms are fulcrumed between the curved brackets 30 30', the arm 29having attached to its inner end the hook-forming die, while the arm 29'at its inner end carries the hammer for closing the side seam of thecan-body blanks. The movement of the arms 29 29' is so timed that thetools carried thereby act upon the canbody blanks the moment they cometo a state of rest at such points of the anvil-bar as to place thecan-body blank beneath the respective devices, while the actuatingmechanism for the oscillating rod 25 is so timed as to throw the saidrod to raise the anvil or hammer plate 23 the moment the can-body blankis brought to a state of rest upon the cylindrical portion of theanvil-bar 14. After the side seam has been closed by the hammer 21 anopposite throw or movement is given to the rod 25, which permits of themandrel or hammer plate lowering in order to allow of the formedcan-body being easily slipped from ot the cylindrical portion of theanvil-bar 14. As the inner end of the arm 29' is raised the stepmovement of the endless carrier forces the formed can-body onto thecurved guide-track 31, which connects the inner end of the anvil-barwith the longitudinal T-shaped extension 32. longitudinal extension 32may be said to constitute a continuation of the anvil-bar, inasmuch asthe adjoining ends of the section 31 and the anvil-bar and the adjoiningends of the said section 31 and the section 32 are bolted together.Sagging of the section 32 is obviated by reason of the fact that thesame is upheld by the inwardly-extending brackets 12' of the links ofthe under run of the endless carrierbearingagainst the flanges 32',laterally extending from a guide-plate 33, attached to the head of theT- shaped extension 0r section 32, Fig. 3 of the This curved guide-trackand the` IOD IIO

drawings. Within this guide-plate moves the tongue 13 of the links 7 ofthe endless carrier. In the face of the curved guide extension orsection Y3l is formed a guideway 33', into which lits theinwardly-projecting bead of the side seam. The can-body is thus heldagainst side slippage as conveyed to- Ward the section or extension 32.As the formed can-body is carried upon the extension or section 32 incase the same is to be soldered its side seam is iirst presented to theflux-applying device 34 and then to the soldering device 34'. When theend ofthe extension or section 32 is reached, the formed can-body isforced therefrom by the movement of the endless carrier and deliveredinto can-runway 35. An intermittent movement is imparted to the endlesscarrier by the rolls 35', secured to studs projecting from the gear 36,alternately engaging with the radial slots 36', cut in the disk 37,secured to the shaft 5', Fig. 2 of the drawings. The gear 36 is drivenbythe intermeshing pinion 37', mounted upon the drive-shaft 38. The gear36 is mounted upon a cross-shaft 39'. To the opposite end of thecross-shaft 39' is attached the gear 38', which meshes Witlra pinion 40,mounted upon the short shaft 392. Upon this shaft 392 is mounted thebevelgear 393, which drives corresponding gear 394 on the inner end ofshaft 28.

The ean-body-blank feed-roll l5' `is driven by the inter-meshingbevel-pinions 40' 402, the latter being secured to the inner end of theshaft 4l. This shaft is driven from the driveshaft 38 by means of asprocket-chain 42, working over the sprocket-wheels 42' 43.

The conveyer or feed chain for the can-body blanks Works oversprocket-Wheels 43 432, the former being mounted upon the shaft 28.

A more detailed description as to the drive mechanism, the Working ofthe feed-mechanism for the can-body blanks, and the working of thehook-forming and seam-closing mechanism is not deemed necessary,inasmuch as the same is substantially that set forth in my formerapplication, heretofore referred to.

Having thus described the invention, What is claimed as new, and desiredto be protected by Letters Patent, is-

l. In a can-body-forming machine,the combination With an intermittentlynon-reciprocating endless carrier, of an anvil-bar, means for forming'acan-body blank around the anvil-bar, means coacting with 'the anvil-barfor forming interlocking hooks in the side edges of the can-body, meansfor closing theside seam, an anvil or hammer plate against which saidmeans Works, devices carried by the endless carrier for moving thecan-body upon the anviilbar, and means for actuating the anvil or hammerplate during the operation of the machine.
